Does beta-interferon prevent multiple sclerosis relapses associated with poor air quality and viral infections in multiple sclerosis patients?
Beta-interferon appears to protect multiple sclerosis patients from relapses triggered by high ambient air particulate matter and viral infections.
May support beta-interferon mitigating MS relapse risk from PM10 or adenovirus; leaves open randomized confirmation.
BACKGROUND: The monthly multiple sclerosis relapse rate was studied from January 1995 to March 2001 from hospital records in Southwestern Finland as a retrospective open-label study. METHODS: The relapse rates of beta-interferon users and nonusers were compared to ambient air inhalable particle levels and viral infections in the population with logistic regression. RESULTS: In the non-user group, relapses were more frequent 1 month following the episodes when PM(10) was in the highest quartile [logistic regression odds ratio = 1.196 (95% CI = 1.019-1.404), p = 0.028] and following adenovirus epidemics in the general population [logistic regression odds ratio = 2.234 (95% CI = 1.013-4.926), p = 0.046]. PM(10) and virus infections had no significant effects in interferon users. CONCLUSION: In addition to being antiviral, interferon also protected multiple sclerosis patients against an enhanced susceptibility to infections caused by PM(10).
